Colorado Unit 85 Elk Hunting Guide

Colorado Unit 85 is a limited-quota elk unit tucked into the southern part of the state, spanning 751,836 acres of rugged, high-relief country that climbs from 5,988 feet up to 13,560 feet in elevation. For hunters researching this unit, the first thing to understand is that there is no general season here — every elk hunt in Unit 85 is a limited-quota draw hunt, including tags for antlered and either-sex animals. That structure changes how hunters should think about the unit compared to nearby over-the-counter areas, and it's worth digging into the numbers before deciding whether to spend an application on it.

This is public-land-limited country. With only 18% of the unit in public ownership and just 3% designated wilderness, hunters need to plan access carefully rather than assuming they can simply pick a drainage on a map and start hiking. Forum chatter around Unit 85 repeatedly points to national forest ground as the go-to public option, which lines up with the reality that the majority of this unit sits in private hands.

HuntPilot Analysis: Is Unit 85 Worth Applying For?

The honest answer is that Unit 85 rewards hunters who draw a tag and do their homework, but it's not a slam-dunk unit for everyone. Because every hunt here runs through the draw, hunters are not competing with unlimited OTC pressure — that alone is a meaningful advantage over Colorado's over-the-counter units, where crowding is a constant complaint. The limited-quota structure keeps hunter density more controlled, which shows up in the harvest data.

Recent harvest figures compiled by HuntPilot show real movement year to year. In the 2025 season, 1,616 hunters harvested 478 elk for a 30% success rate — a notable jump from 2024, when 5,750 hunters harvested 1,228 elk for a 21% success rate, and 2023, when 5,690 hunters posted 1,024 harvests at an 18% success rate. That swing from roughly 18-21% success in 2023-2024 up to 30% in 2025, paired with a steep drop in hunter numbers (from over 5,700 down to about 1,600), suggests either a significant reduction in tag allocations, a shift in hunt structure, or both. Hunters should treat 2025 as a strong data point but not assume it repeats every year — the multi-year trend of roughly 18-21% success with heavy hunter pressure is the more consistent baseline from 2023 and 2024.

On the herd health side, the picture is more cautionary. Wildlife survey data spanning six years from 2018 to 2024 shows an average bull-to-cow ratio of 27:100. That's a low ratio by elk management standards, and it signals a herd with relatively few bulls per hundred cows — likely the product of consistent hunting pressure on bulls over time, herd management objectives, or a combination of both. Hunters should not expect abundant bull sightings relative to cow numbers, and this ratio is a meaningful data point to weigh against the unit's draw difficulty.

Trophy potential in the counties overlapping Unit 85 is moderate. There is a documented history of trophy-class elk coming from this general area, but it isn't among Colorado's elite trophy pedigree units. Because record-book entries are logged by county rather than by hunt unit, the trophy history associated with Unit 85 is shared with neighboring units that fall in the same counties — an animal credited to this area could technically have been taken in an adjacent unit. That caveat matters when comparing Unit 85 against neighboring units for bragging rights. Given the moderate trophy history, hunters should view Unit 85 as a solid opportunity unit rather than a unit chased specifically for record-book potential.

Put together: Unit 85 is worth applying for if a hunter values a controlled-pressure draw hunt over unlimited OTC chaos, and if their expectations are calibrated to a working bull population rather than a trophy-heavy one. The 2025 harvest numbers are encouraging, but the low bull:cow ratio and limited public land access mean this unit demands real scouting effort and flexibility once a tag is drawn.

Access & Terrain

Unit 85's terrain profile is defined by extreme elevation range — from valley floors near 5,988 feet up to alpine peaks topping out at 13,560 feet. That's more than 7,500 feet of vertical relief within the unit boundary, meaning hunters could be glassing sagebrush foothills in the morning and working timbered high-country basins or above-treeline terrain by afternoon, depending on where they draw a tag and where elk are holding.

The access situation is the more critical planning factor. With only 18% of the unit classified as public land, the majority of Unit 85 is privately held. This is below the threshold where a unit can be called DIY-friendly, and hunters need to identify which specific blocks of public ground are huntable before ever committing to this unit. Forum discussion around Unit 85 consistently points to national forest ground — specifically San Isabel National Forest and the Spanish Peaks area — as the primary public access options, which aligns with the low overall public land percentage; hunters are funneling into a relatively small footprint of accessible ground.

Wilderness acreage is minimal at just 3% of the unit, so hunters won't find the kind of large roadless wilderness complexes that force serious backcountry commitment in other Colorado units. This is a double-edged sword: it means more of the public land here is reachable without multi-day pack-ins, but it also means public ground sees concentrated pressure since there's less remote habitat to spread hunters out.

Given the private land majority, hunters serious about Unit 85 should scout well before their hunt to confirm public land boundaries precisely, since public and private parcels are often interspersed in checkerboard patterns typical of this part of Colorado. One forum poster planning a first elk hunt in this unit noted having only three days to scout before the season — a tight window given the terrain's complexity and the limited public footprint. Hunters in a similar position should lean on mapping tools that clearly delineate public versus private boundaries down to the parcel level before setting boots on the ground.

Harvest Success Rates

The three-year harvest trend in Unit 85 tells an important story. Success rates climbed from 18% in 2023 to 21% in 2024 to 30% in 2025, even as total hunter numbers dropped dramatically — from 5,690 hunters in 2023, to 5,750 in 2024, down to just 1,616 in 2025. Fewer hunters afield combined with a similar or improved total harvest count (478 elk in 2025 versus over 1,000 in each of the prior two years, though on a per-hunter basis 2025 was clearly more efficient) points to a meaningful shift in how tags are being allocated in this unit.

Hunters should not assume the 30% success rate is now the standard going forward without checking current-year tag numbers on HuntPilot's Colorado page, since a nearly 75% reduction in hunter numbers between 2024 and 2025 is a substantial structural change. For planning purposes, the 2023-2024 data — with success rates in the high teens to low 20s under heavier hunter density — may be the more conservative and reliable baseline, while 2025 shows what's possible when tag numbers are tightened.

Trophy Quality

Trophy potential in the counties overlapping Unit 85 is best described as moderate. There is a documented history of trophy-class bulls coming out of this region, giving hunters reason to believe a mature bull is possible, but the production hasn't been consistent or heavy enough to place this unit among Colorado's top-tier trophy destinations. Because these records are attributed at the county level rather than to Unit 85 specifically, the same trophy history is shared with adjacent units overlapping the same counties — so a hunter can't assume every recorded bull came from inside Unit 85's exact boundary.

Combined with the low average bull:cow ratio of 27:100 recorded across the six surveyed years, hunters should temper trophy expectations. A low bull:cow ratio generally correlates with fewer mature bulls surviving to trophy age, since it reflects a herd structure skewed more heavily toward cows relative to bulls. Hunters chasing a genuine trophy-class bull in Unit 85 should treat it as a possibility worth pursuing with patience and good scouting, not a probability baked into the unit's reputation.

Herd Health & Population Trends

The wildlife survey data available for Unit 85 covers six survey years between 2018 and 2024, with an average bull-to-cow ratio of 27:100. This is a relatively low ratio and suggests a herd structure that leans heavily toward cows, likely the result of sustained hunting pressure on bulls, active herd management, or both over the survey period. Hunters should read this ratio as an indicator of what to expect in the field: more cow and calf groups relative to bulls, and bulls that may be more dispersed or holding in smaller, more scattered bachelor groups by the time hunts occur later in the year.

Without survey-by-survey historical detail beyond the six-year average, it's not possible to say definitively whether this ratio has been trending up or down within that window, but the average itself is a useful benchmark for setting realistic expectations. Hunters who've drawn a tag here should factor this into their strategy — glassing larger open basins and transition zones where cow-heavy groups congregate may produce more elk sightings overall, even if bull encounters are comparatively less frequent.

How to Apply

Every elk hunt in Colorado Unit 85 runs through the state's limited-quota draw system — there is no over-the-counter or general season option here, so hunters must apply and be selected to hunt this unit. Colorado's draw operates on a preference point system, where residents and nonresidents apply in separate pools and points play a direct role in draw priority; higher point totals improve a hunter's position, and Colorado's system does allow a sufficiently high point total to effectively guarantee a tag on many hunts, unlike weighted-lottery states.

Nonresidents should expect this to be a longer-term point-building proposition on a limited-quota unit like Unit 85, since every hunt code here draws from a capped pool rather than unlimited OTC availability. Residents without points may still have a shot depending on quota levels for a given hunt, but building preference points over multiple application cycles improves the odds considerably.

Application dates, fees, and current draw odds for Unit 85 change every cycle and are not included here — for the most current deadlines, license fees, and draw statistics, hunters should check HuntPilot's Colorado state page at /states/co before applying.

Frequently Asked Questions

Is Colorado Unit 85 a draw-only unit for elk? Yes. Unit 85 has no general season for elk — every hunt in the unit, including antlered and either-sex tags, is issued through Colorado's limited-quota draw. Hunters cannot buy an over-the-counter tag for this unit.

What is harvest success like in Unit 85? Recent data shows success rates of 18% in 2023, 21% in 2024, and 30% in 2025, though hunter numbers dropped sharply between 2024 and 2025 (from 5,750 down to 1,616), which likely explains much of the improvement. Hunters should check current tag allocations before assuming the 30% figure is the new normal.

How big are the elk in Unit 85? Trophy potential is moderate. The counties overlapping this unit have a documented but not exceptional history of trophy-class bulls, and that history is shared with neighboring units in the same counties. A low average bull:cow ratio of 27:100 across recent survey years also suggests fewer mature bulls relative to cows, which tempers trophy expectations somewhat.

What is the terrain like in Unit 85? The unit spans an extreme elevation range from 5,988 to 13,560 feet across 751,836 acres, meaning hunters can encounter everything from lower-elevation foothill terrain to high alpine basins. Public land makes up only 18% of the unit and wilderness just 3%, so most huntable public ground is concentrated in specific national forest blocks rather than spread evenly across the unit.

Is Unit 85 worth applying for? It depends on what a hunter is after. For those willing to navigate a private-land-majority landscape and put in real scouting time on the limited public ground available, Unit 85 offers a controlled-pressure draw hunt with reasonable harvest success in recent years. Hunters chasing an elite trophy unit or an easy-access DIY experience may find better options elsewhere, but as a solid limited-quota elk unit with real opportunity, Unit 85 earns consideration.
